Well I kinda want the same thing however, the only problem is that Emily and Emma have a husband. I think that perhaps Emily or Emma can fake her death and leave the island with Louis if the player chooses to romance Emily in Episode 1. Also there are many mysteries around Emily and Emma that have yet to be explained.
Did anyone catch the reference Louis tells his mother when she explains that Mortimer is a demon? The one where he says something like "What's next? An ancient monster with a head like an octopus?" I believe that was put in there because of Focus Home Interactive's next game they are releasing which is Call of Cthulhu.
